SYNTHESIS, SPECTRAL CHARACTERIZATION AND THERMAL BEHAVIOUR OF NEW METAL(II) COMPLEXES WITH SCHIFF BASE DERIVED FROM AMOXICILLIN

Metal complexes of Schiff base derived from different antibiotics are widely employed as biological active materials, especially as antibacterial agents. Two new metal (II) complexes with the Schiff, base (HL) derived from amoxicillin and salicylaldehyde were synthesized and investigated using eleme...
